What is portuguese sausage?

I still don’t know but it taste good. We had breakfast at Koa Pancake house. It is amazing. We were told to try the portuguese sausage. Does anyone know what the difference between regular sausage and Portuguese sausage is?
Koa Pancake house is amazing. We don’t have anything like this back in Pittsburgh.
Not only are the pancakes delicious, but the hot chocolate comes with sprinkles too.
